Abstract:Track systems consisting of a continuous concrete support, subbase, and compacted subgrade provide possible solutions to problems of continuing and costly track maintenance. Such concrete slab track systems have been built in the past 25 years by railroads and transit authorities in several countries. A review of details of major slab track projects is presented. Methods of constructing slab track systems are outlined, and performance of slab track projects is discussed. Features of slab track systems are compared with those of conventional ballasted track. The growing interest in concrete slab track systems is justified by reduced maintenance, reduced traffic disruption, improved performance, improved stability, and expected long service life.*
